GMMTV did a great job with marketing 2gether. I was hooked since they dropped the first trailer. I was always excited for Fridays. At least the first 8 weeks or something.

Story

And the first few episodes did not disappoint me: I really liked the characters and thought that they were likable.
But when the fake dating ended -as mentioned by other users- the real relationship seemed less real than the fake one. It has nothing to do with that they did not kiss or had a sex scene. This is definitely due to the lack of character development, filling the plot with unnecessary drama and then rushing everything in the end. There was no spark between Tine and Sarawat. It just felt weird, because they did not act like a couple, they acted like best friends (that high five).
They really didn't fix anything between them during that concert scene and then they gave us a music club scene instead of them talking alone in the apartment or whatever. It just felt so weird.

Characters
For me it seemed like Tine always stayed the same, it maybe actually seemed like his insecurities got worse. Sarawat turned from being a funny, interesting, likable character into an asshole. The last two episodes he was so out of character. I still can't understand how that happened.

I really liked Man and Type and I wish they would've taken more time to develop them. They really saved the last episode for me.

I don't want to talk about the mess that is Mil and Phukong. What even is that? Phukong deserves better.

If you can't handle your main couple, don't start developing another one.

Production
I don't know who planned this whole thing, but it was definitely a mistake to film the concert scenes so early. Im quite sure that they filmed the Scrubb scenes in one day or maybe two. That's why the chemistry feels so off in the final episode because Bright and Win probably weren't that comfortable around each other yet.
Also what is up with Bright's hair? Like who approved that? It changes from scene to scene. GMMTV should work on their production coordination. I know that it is not easy, but these are mistakes that can easily be fixed by more accurate planning and not trimming your actor's hair midway or stopping to trim it after starting filming.

Editing & Music
The Editing sometimes was sloppy and I felt like I missed something when I didn't. Also what is up with them using the clip-on-microphone sound, when the actors are grabbing their shirt (Tine crying in Ep 12) or are laying on a sofa? The boom operator is there for a reason. The sound-design is disappointing in most Thai-dramas, so I won't complain too much.
I really liked the original songs and listen to them occasionally, but the "score" just sounded like library music.

Overall
I think I will rewatch it when I'm bored and I would still recommend it if you're searching for something cute, where you don't have to think so much.
